Welcome! I am an Associate Professor at the Department of Mathematics and Statistics, Boston University. I am also affiliated with the Center for Information and Systems Engineering, Boston University
and I am a junior faculty fellow at the Hariri Institute at Boston University. I completed my PhD at the
Department of Mathematics, University of Maryland at College Park, advised by Professor Mark Freidlin and I was at
the Division of Applied Mathematics, Brown University
as a Prager Assistant Professor from 2009-2012.
My undergraduate studies were in Applied Mathematics and Physics at the National Technical University of Athens in Greece.
(NTUA).
Research interests:
My research lies broadly in the area of stochastic processes, applied mathematics and probability, large deviations, multiscale methods, financial mathematics, asymptotic problems for stochastic processes and partial differential equations , statistical inference for stochastic differential equations and statistical learning. In particular:
- Asymptotic Problems for Stochastic Processes and Partial Differential Equations (PDE's) such as Multiple Scale Problems and Large Deviations
